When you start dictating with Mumble by holding down your dictation shortcut (e.g. Fn), a small panel appears showing a row of format shortcuts. Dictation panel While still holding the dictation key, tap any of these shortcut keys to change how your text will be formatted. For example, ← for Concise, ↑ for Bullets, or / for AI Skills. Release the dictation key when you’re done, and the formatted result is inserted. You can press a format shortcut at any point while dictating (before, during, or after speaking), as long as you’re still holding the dictation key.

​
How the panel works

  1. Hold your dictation shortcut (Fn by default, customizable in Settings > Shortcut) and start speaking.
  2. While still holding, press a key to choose an output format (optional).
  3. Release to insert the result at your cursor.
If you don’t press any key, Mumble uses the default action (← Concise).

​
Output actions

While holding your dictation shortcut, press one of these keys to pick how your speech is processed. The selected action highlights in the panel. ← Left arrow: Concise. Polishes your speech into clean text. Fixes grammar, punctuation, and formatting. This is the default.

Learn how to create one in the Set up a custom prompt section below. If you don’t want the panel to show at all, click Disable all at the top of the section. The panel won’t appear during dictation.

Custom prompt ideas

Your prompt can be anything that transforms text. A few examples:
  • Translate. “Translate into Spanish.” Dictate in English and get Spanish output.
  • Change tone. “Rewrite in a formal, professional tone.” Turn casual speech into polished writing.
  • Shorten. “Condense to one paragraph.” Get a tight summary of a longer thought.
  • Reformat. “Rewrite as a numbered step-by-step guide.” Turn spoken instructions into structured steps.
